The Karnataka High Court has issued a notice to the State government regarding the environmental impact of the ₹1,130 crore Hebbal tunnel project. The court warned of a potential stay if a response is not filed by August 24.

Key Takeaways

  • Karnataka HC seeks state response on the impact of the Hebbal tunnel project on the lake.
  • The court warned of staying the project if the government fails to respond by August 24.
  • Petitioners challenge the constitutional validity of reduced lake buffer zones.
  • The project is a 2.2 km twin tunnel estimated at ₹1,130 crore.

The High Court of Karnataka on Thursday issued a notice to the State government regarding a Public Interest Litigation (PIL) questioning the construction of a 2.2 km long, three-lane twin tunnel project. The project, which aims to connect Hebbal junction to the Karnataka Veterinary, Animal and Fisheries University (KVAFSU), is estimated to cost ₹1,130 crore.

Court Issues Stern Warning

A division bench comprising Chief Justice Vibhu Bakhru and Justice K.S. Hemalekha orally warned the government that the project could be stayed if authorities fail to file a written response to the concerns raised by the petitioners before the next hearing on August 24. The court specifically directed the government to file an affidavit clarifying whether any study has been conducted regarding the project's impact on the Hebbal Lake ecosystem.

Legal and Environmental Challenges

The petitioners, including technocrat Guruprasad R.K. and Elizabeth Soumya of the Hebbal Nature Society, argue that the project poses a severe threat to the ecologically sensitive lake. A major point of contention is the Karnataka Tank Conservation and Development Authority (Amendment) Act, 2025, which significantly reduced buffer zones around lakes. The petition claims this reduction is scientifically unsound and designed to facilitate the tunnel project.

Why This Matters

BozokMedia analysis shows that this litigation highlights the growing tension between rapid urban infrastructure expansion and environmental sustainability. The tunnel's proximity to the lake—only 8-12 meters away according to the DPR—raises critical questions about groundwater movement and flood risks in Bengaluru.

Legal experts suggest that the challenge to the buffer zone amendments could set a major precedent for lake conservation across India.
